Motor: Connects the brain and spinal cord to muscles to stimulate movement.

When we move, the brain sends a message to the spinal cord. From there, the nerves carry the message to the necessary muscles to make them contract and produce movement. Similarly when we touch an object, sensory information is carried through the nerves to the spinal cord and then to the brain so that we can make sense of that information.

Symptoms of Peripheral Nerve Disorders

Peripheral nerve disorders distort or interrupt messages sent between the brain and the rest of the body. This can result in:

Painful cramps

Numbness

Muscle weakness (most common symptom)

Tingling or burning

Unlike the brain and spinal cord, peripheral nerves can regrow after an injury. However, surgery is often required to reconnect the peripheral nerves so that movement and sensation can be restored.
